A 50-ohm RF Dummy load and in-line wattmeter
must be
connected to the main antenna jack in all
procedures that
call for transmission, except where
specified otherwise.
Correct alignment is not possible with an
antenna.
After completing one step, read the
following step to determine
whether the same test equipment will be
required.
If not, remove the test equipment (except
dummy load
and wattmeter, if connected) before
proceeding.

Correct alignment requires that the ambient
temperature
be the same as that of the transceiver and
test equipment,
and that this temperature be held constant
between 68 °F~
86°F (20°C ~ 30°C). When the transceiver is
brought into
the shop from hot or cold air, it should be
allowed time to
come to room temperature before alignment.

Whenever possible, alignments should be made
with oscillator
shields and circuit boards firmly affixed in
place.
Also, the test equipment must be thoroughly
warmed up
before beginning.

Note: Signal levels in dB referred to in
this procedure are
based on 0 dBμ = 0.5 μV (closed circuit).

Under no circumstances should any
alignment be attempted
unless the normal function and operation of
the transceiver
are clearly understood, the cause of the
malfunction
has been clearly pinpointed and any faulty
components
replaced, and the need for realignment
determined
to be absolutely necessary.

The following test equipment (and thorough
familiarity
with its correct use) is necessary for
complete realignment.
Most steps do not require all of the
equipment listed,
but the interactions of some adjustments may
require
that more complex adjustments be performed
in a sequence.
Do not attempt to perform only a single step
unless
it is clearly isolated electrically from all
other steps.
Rather, have all test equipment ready before
beginning,
and follow all of the steps in a section in
the order they
are presented.
